Leviticus 25:50-52

Amplified Bible, Classic Edition

⁵⁰ And [the redeemer] shall reckon with the purchaser of the servant from the year when he sold himself to the purchaser to the Year of Jubilee, and the price of his release shall be adjusted according to the number of years. The time he was with his owner shall be counted as that of a hired servant.

⁵¹ If there remain many years [before the Year of Jubilee], in proportion to them he must refund [to the purchaser] for his release [the overpayment] for his acquisition.

⁵² And if little time remains until the Year of Jubilee, he shall count it over with him and he shall refund the proportionate amount for his release.
